Method Details

setInternalID

public void setInternalID(long internalID,
 ValueStoreRevision revision)

Description copied from interface: LmdbValue

Sets the ID that is used for this value in a specific revision of the value store.

Specified by:

setInternalID in interface LmdbValue

getValueStoreRevision

public ValueStoreRevision getValueStoreRevision()

Description copied from interface: LmdbValue

A blank node identifier.

init

protected void init()

equals

public boolean equals(Object o)

Description copied from interface: BNode

Compares this blank node to another object.

Specified by:

equals in interface BNode

Overrides:

equals in class AbstractBNode

Parameters:

o - the object to compare this blank node to

Returns:

true, if the other object is an instance of BNode and their IDs are equal; false, otherwise.
